To all whom it may concern."

Be it known that 1, JOHN W. PAUL, a citizen of the United States, residing at Kitten- -ning, in the county of Armstrong and State of Pennsylvania, have invented new and useful Improvements in Type-Writing Machines, of which the following is a specification;

This invention relates to typewriting machines and consists in certain im rovements in the construction thereof as wil be hereinafter fully described and pointed out in the claims.

More particularly the invention relatesto that part of a typewriting machine relating to the ribbon actuating mechanism.

The invention is illustrated in the accompanying drawings as follows: I Figure 1 shows a section on the line 11 in Fig. 2. Fig. 2, a section on the line 22 in Fig. l. Fig. 3 a rear eleuatiorr f the ribbon mechanism carrying plate with the assembled mechanism thereon. Fig. 4, an end elevationv of the same. Fig. 5, a section on the line 5 in Fig. 3.

1 marks the frame as a whole; 2 the side of the frame; 3 a cross piece at the rear of the machine; 4 a cross plate extending horizontally across the machine above the cross iece 3; 5 a downwardly extending lip from front'of the cross plate 4; 6 the carriage and 7 the platen.

The ribbon spools 8 are mounted on a rib-.

bon mechanism carrying late 9. This late-is ordinarily formed of s eet metal and as the ears 10 formed at its ends by means of which it may be removably attached to the frame. In this way the entire ribbon actuating mechanism is self contained and can be assembled on this plate, and after being assembled the plate mounted in the frame. This facilitates the manufacture of the mechanisms.

The ribbon spools are mounted on the shaft 11 and a gear 12 is fixed on this shaft. The gear 12 meshes a pinion 13. The pin.- ion 13 is fixed on a shaft 14. A miter gear is arranged on the shaft 14 in position to be engagedby a gear 16 on a cross shaft 17. The cross shaft 17 .is slidingly mounted in the bearing lugs 18 secured to the plate 9. By shifting the shaft 17 the ears 16 may alternately be moved into an out of mesh with the gears so that the movement of the ribbon may "be reversed. A pinion 19 is slid-' vided with the groove 20 in which is arranged a pin 20' which locks the gear against rotation on the shaft. The plate 19 holds the gear against movement longitudinally, but

permits the shaft to move in order to reverse the gears 16. The gear 21 is mounted on a shaft running in a direction from front to rear ofthe machine and is in mesh with the ear 19. A bearing bracket 22 extends rom the plate 9 and with the plate 9 forms a bearing for the shaft. A pimon 23 is fixed on the inner end of the shaft 22. It is in mesh with the gear 24. The gear 24 is journaled on a shaft 25. by a post 26 extending upwardly from the p ate 4. The This inion is xed on a shaft28. the shaft 28 being journaled on the post 26. An escapement wheel 29 is fixed in the front end of the shaft 28. The dogs 30 and 31 are mounted on a reciprocating rod 32 and act on the wheel 29 to permit of its escapement.

The link 33 extends from the rod 32 to the universal bar 34 and communicates the movement of the universal bar to the rod 32 so that as the universal bar is depressed the rod 32 is reciprocated to act on the escapement mechanism. The universal bar is mounted on the levers 35, one at each side of the machine and these levers are pivoted on a rod or pin 36 arranged on the hangers 37. The hangers 37 project downwardly from the plate4. The levers act upon spring socket 35 which tends to hold the levers in the upper position. A ribbon carrier guide plate 38 is secured to the ribbon mechanism carrying plate 9 by means of the screws 39. The ribbon carrier 40 projects under this plate and has the cars 41 which hold the caractuating rod 48 extends across the machine and hasthe arms 49 extending from it into slots 50 in the ribbon carrier. The arms 49 have-slots 51 in theirends which engage the pins 52 on the ribbon carrier so that as the rod 48 is oscillated the ribbon carrier is reciprocated.

An arm is secured to the end of the rod 48. crank lever 55 is fixed on a stud 56 secured to the side 2 of the frame. A pin extends from one arm of the bell crank lever into the 53 having the cam slot 54 thereon The shaft is supported ear 24 meshes a pinion 27.

A bell won an arm 65 of a lever 66.

- bar60 and swinging the bell crank lever 55.

V of the ribbon carrier, the ribbon carrier being cates' the ri cam slot 54. The auxiliary arm of the bell y crank lever hasa slot 58 which engages a in 59 on the'end of thecurved lever 60. he curved lever is fixed at 61. A link 62 1s connected with the curved lever by means of a sliding block 63. The link is ivoted at 64 he levers 66 are arranged at each side of the machine and are pivoted on the pins 36. The levers 66, one at each side of the machine have a connecting bar 68 which forms a universal bar for the machine. Some of the key levers 69 have a notch 70 arranged thereon so that while they operate the universal ribbon bar 68, they do not o erate the universal bar 34. The purpose of t -s is to permit of the actuation of some type bars without 0 erating the escapement. This is particular y desirable in relation to some characters, especially in some of the foreign languages. Aspring 71 extending from the plate 4 to the lever 66 tends to hold the lever in its upper position.

The lever 60 is curved with an arc having the pivot 64 as a center so that the link 62 ma be moved along the lever 60 without shi ting the position of the lever 60.. This shifting of the mechanism, however, changes the action of the-link 62 on the end of the lever 60. The purpose of this is to permit of the use of a plurality color. ribbon. When it is desired to use one color, one part of the block 63 may be adjusted on one end of the lever 60 as shown in Fig. 1. .When' a different color is used the block 63 may be shifted on the curved lever 60. This-will not'change the initial position of the ribbon carrier, that is the ribbon carrier will return. to its initial position each time, but it will vary the throw moved a greater distance as the block 63 is moved toward the pivot 61. The link 62 has an extending arm.72 which protrudes through the side of the machine and is revided with a handlev 7-3 bymeans of -w 'ch the link may be moved from one position to another as desired so as to shift the. part of ribbon to be used.

The operation of the ribbon carrier mechanism may be readily followed: The ribbon bar 68'is depressed. It carries the link-62 downwardly'thus' carrying down the curved The bell crank lever 55 acting through the cam arms 53 oscillates the shaft 48 and the shaft acting thropgh the arms 49 reciprobon carrier 40. i What I claim as new is: 1; In a front strike typewritin machine the combination of a universal ri bon bar; ribbon bar levers carrying the ribbon bar; a link pivotally connected to the barlever; a pivoted lever curved in an arc with the pivotal connection between the link and ribon bar lever as a center; a connection-between the curved lever and the link; a ribbon carrier slidin ly mounted; a rock. rod; a rock arm extendmg from the rod tothe arm for reciprocating the carrier when the rod is oscillated; a cam arm on the rock rod; a bell crank lever, one end of which operated onthe combination of the universal bar; a universal ribbon bar; levers at eachside of the.
